There is currently a minor bug with quests where you can't view other pages from other users on their profile.
I noticed that when you do it on your profile, the URL changes and adds the number of the page like so;
http://armorgames.com/user/fantasy4life/2
But if you go on another persons profile and click a page, it changes to this one for example;
http://armorgames.com/user/fantasy4life/fantasy4life/2
It copies the username twice, which in turn doesn't change the page since it's a faulty URL.
